(quoted from post at 02:46:04 11/16/1 While Cletrac engines can be a problem for spares (more particularly the oil burners, I think), it is usually the undercarriage which is the
expensive part, if completely shot. This one does not look too bad, and anything can be rectified, but this can be the expensive part of restoring
a crawler to tip-top running condition.

I would get power to the starter motor and check that oil pressure can be raised (without spark plugs in place) before trying to start the engine.

Okay, I hooked power to the starter, the engine spins freely! (with the plugs out of course)

The rear sprockets looks pretty good, so I assume the tracks aren't too bad. Everything looks reasonably decent. I say it is worth fooling around with until you find something seriously wrong with it. As mentioned below, contact Landiss Zimmerman. He will steer you right. I redid a family OC-4 and got everything I needed from Mr. Zimmerman. He has a ton of parts around for Oliver/Cletrac. His brother also has a foundry where they cast some new parts.

(quoted from post at 18:04:56 11/18/1 Just about all straight six cylinders engine firing order is 15 36 24. Does it run if you spray some parts cleaner in the intake.

It's cranks over, once in a while it'll pop. Yes I was spraying some starting fluid. I pulled the plugs multiple times and put a few drops of gas in each cylinder. I have my hand over the carb as a choke. But that's all I'm gettin. Tried for a few hours today...

It won't do anything until you rebuild the carb. You'll just be wasting time and even if it starts, you'll still have issues. Get a kit, run fuel from a bypass tank or something to get it going.

I took the carb apart and cleaned everything, but I didn't have a rebuild kit. I reused everything. That could be one of my problems I guess. Zimmerman mentioned forget this carb and buy a rebuilt Zenith from him for $270, since there's nothin available for the Tillotson.

Okay so I have some stuck valves. LOL. 0 psi on all cylinders except number 5, 80 psi. I pulled the intake/exhaust manifold and the head off. Think I'm gonna do a quick valve job. Nothin I cant handle.

Alright today I pressure washed the head and intake/exhaust manifold, then did a real quick bead blast job. Good enough. LOL

I cleaned the top of the block, pistons, wiped the bores out and wire wheeled everything. My father is coming over today with a valve spring tool so I can remove the valves. I'll bead blast those too. More to come.

So........from what I found out why it was parked, my wife's brother mentioned it needed planetary gears, or they were broken, or something of that matter, he couldn't remember exactly, but for sure had something to do with the planetary gears.

Are these something that could be rebuilt?

Planetaries? I doubt the gears themselves are bad. My guess would be if it's like the other Cletrac/Olivers, the bushings may be bad or the brake bands need relining.

Been real busy this month but was able to get stuff done the past 3 weeks. I took the radiator apart. Not as bad as I thought. I think I can work with this core. Couple of tubes I'll need to block off, but should be fine. Experimenting with paint. Caterpillar yellow is off, then I went with orange, which isn't right either, but it sure looks close to the Cletrac orange, of which I ordered a case of it.
